(weee directive 20 12 / 19 /ec ) when does the weee directive take effect? the directive came into effect internationally on july 04 , 20 12 . what is rohs ( 20 11 / 6 5/e u )? the goals of the directive are to: ? place less of a burden on human health and to protect t he environment by restricting the use of hazardous substances in new electrical and electronic devices ? to support the weee directive (see above) rohs enforces the restriction of the following 6 hazardous substances in electronic and electrical devices: ? le ad (pb) C no more than 0.1% by weight in homogeneous materials ? mercury (hg) C no more than 0.1% by weight in homogeneous materials ? cadmium (cd) C no more than 0.01% by weight in homogeneous materials ? chromium (cr6+) C no more than 0.1% by weight in homogen eous materials ? pbb, pbde C no more than 0.1% by weight in homogeneous materials
